We were cooking last night and my wife heard a pop in the stove. When checked the circuit breaker had flipped, so i reset and the oven is working which is on the same circuit but the cook top stove wont turn on. There is power to the stove. Took the stove apart and found 4 infinite switches. The one that has the power going to it has a burn mark on it. The power goes to that switch i think its called the duel infinite switch, and then gets feed to the other 3. Any suggestions on how to fix, i think its the duel infinite switch. There really is not o much to the units.

I think you have a power problem.
Each infinite switch is a separate device.
Although power to them may run off/from another switch they do not get power through that switch. They are just using the connectors on the switch as a tie/common connection.
I hope I explained this OK.

I would check that the unit is actually getting the correct power.
It does sound like the one infinite switch may be toast but it may have also blown the wire feeding the cooktop.

Does the fan work?
If not you then know that probably the L1 side is blown.
If it does run then L2 is a likely culprit.

L1 to L2 should be 240 volts
L1 to Neutral and L2 to Neutral, both should be 120 volts.
If OK
Unplug the unit and check the wires at the terminal strip in the machine to make sure none are loose or burned out
If OK
Check the power at the terminal strip.Be careful as 240 volts is lethal !!!

I am getting power at all 4 switches about 1.100v on the meter. The fan does not work. All the wiring looks good, the unit is about 2 years old. Is there another switch or power source that feeds the others, or is possible that all 4 infinite switches is bad.
